reaction is exothermic‚ the enthalpy would be negative. During a chemical reaction‚ which consists of breaking and creating bonds‚ heat is either absorbed or released. In this lab‚ the reaction uses the disassociation of an ionic compound ammonium nitrate shown in the equation #1 below into ions. In order to disassociate ammonium nitrate into ions‚ energy is required. Both NH4 and NO3 are always soluble‚ therefore the ionic compound disassociates completely. Through equation #2‚ heat absorbed or released

Researchers have identified the activity of Silver NPs exerted the antibacterial effect in two steps. First‚ they changed the membrane potential and reduced adenosine triphosphate (ATP) synthase activities‚ thus reducing the metabolism process. Secondly‚ they declined the subunit of the ribosome for tRNA binding‚ thus collapsing its biological mechanism. At the same time‚ they proved to be less toxic to mammal cells [26]. Silver NPs with a small size and enhanced surface area produce some electronic

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Lab Questions By Zackary Conte and Justin Dvorsak The first experiment with 1 M sucrose in the bag and distilled water in the beaker had almost exactly the same results. The masses were relatively the same the difference have could been from the amount of liquid that was placed inside of each of the bags. The second experiment with 5% Ovalbumin in the bag and 1 M sucrose in the beaker had almost exactly the same results. The masses were relatively the same the difference could have been from the

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality
